您的Apple iPhone 是否无法在来电时响铃？发生这种情况有几个原因。继续阅读以了解在 iPhone 上取消静音的最佳方法。
如果您的 iPhone 在来电时没有响铃，则可能是它处于静音模式(Silent Mode)。如果这不是原因，则可能是 iOS 功能、设置或软件冲突导致其无法响铃。以下方法应该可以帮助您在 iPhone 上取消静音呼叫。
1.关闭静音模式
静音(Silent) 模式(Mode)是阻止您的 i Phone响铃来电和(Phone)FaceTime通话(FaceTime)的最常见原因。要切换到响铃模式(Ring Mode)，只需轻按i Phone左侧的静音(Silent)开关（音量按钮上方），这样橙色就不会显示在下方。
静音模式 - 关闭(Mode – Off)通知应出现在 iPhone 的主屏幕(Home Screen)上作为确认。
2.增加铃声音量
也有可能您将 iPhone 上的铃声音量设置为太低而无法正常听到。要检查，请打开设置(Settings)应用程序并点击声音(Sounds)和触觉(Haptics)。然后，将铃声(Ringtone)和警报(Alert)音量下的滑块向右拖动以提高音量。
或者，如果您更喜欢使用 iPhone 的音量增大和减小按钮来增加和减小铃声音量，请激活“使用按钮更改”旁边的开关(Down)。
3.关闭请勿打扰/专注
另一个不仅可以使电话静音而且可以阻止它们的功能是请勿打扰(Disturb)（iOS 14 及更早版本）和焦点(Focus)（iOS 15 及更高版本）。要禁用它，请打开控制中心(Control Center)（从屏幕右上角向下滑动或双击主页(Home)按钮）。然后，点击月亮(Moon)图标 ( DND ) 或个人资料(Profile)图标 ( Focus )。
您可能还想检查“请勿打扰(Disturb)”或“焦点”(Focus)是否设置为按计划激活或允许来自特定联系人的呼叫，尽管该功能处于活动状态。有关更多详细信息，请查看“请勿打扰”(how Do Not Disturb)和“焦点”在 iPhone 上的工作原理(Focus works on the iPhone)。
4.检查你的睡眠时间表
如果您在 iPhone 上设置了睡眠时间表，它可能会自动触发“请勿打扰(Disturb)”或“睡眠焦点”(Focus)。因此，这会导致呼叫静音。
要停止这种情况，请打开“健康(Health)”应用，点击“浏览(Browse)”，然后选择“睡眠(Sleep)” 。然后，点击完整计划(Full Schedule)和选项并禁用(Options)使用计划(Use Schedule)进行睡眠焦点(Sleep Focus)旁边的开关（或者如果您想完全禁用睡眠计划，请关闭(Sleep)睡眠(Sleep Schedule)计划）。
如果您的 iPhone 运行的是 iOS 13 或更早版本，请打开“时钟(Clock)”应用，轻点“Bedtime > Options”，然后关闭“就寝时间请勿打扰(Bedtime)”旁边(Disturb)的开关。
5.禁用静音未知呼叫者
为了减少垃圾电话，您的 iPhone 有一个内置功能，可以阻止未知号码(feature that blocks unknown numbers)——那些不在您的联系人列表中的号码。但是，它也可以阻止重要的电话联系到您，而是将它们发送到您的语音信箱。
要禁用它，请打开 i Phone的设置(Settings)应用程序，选择电话(Phone)，然后点击静音未知呼叫者(Silence Unknown Callers)。然后，在以下屏幕上
关闭Silence Unknown Callers旁边的开关。(Silence Unknown Callers)
6.禁用蓝牙设备
如果您经常在 iPhone 上使用Apple 的AirPods等(AirPods)蓝牙(Bluetooth)音频设备，请不要忘记在不使用它们时将其关闭。如果没有，您的 iPhone 最终会通过蓝牙(Bluetooth)耳机提醒您有来电。
如果您的蓝牙(Bluetooth)耳机不在您附近，请尝试禁用 iPhone 的蓝牙(Bluetooth)无线电（打开控制中心(Control Center)并点击蓝牙(Bluetooth)图标）。
在 iOS 14 及更高版本中，AirPods和Beats耳机可能会在未经许可的情况下切换到您的 iPhone 并产生音频问题。要停止这种情况，请转到Settings > Bluetooth，点击AirPods旁边的信息(Info)图标，然后将连接(Connect)到此 iPhone 设置为上次连接(Connect)到此 iPhone 的时间。
7. 摆脱“耳机模式”
如果您使用一副有线耳机，即使您将它们移除，您的 iPhone 也可能会卡在“耳机模式”中。(Headphone)这完全阻止了所有声音输出，包括铃声。发生这种情况时，您会在控制中心(Control Center)的音量滑块上看到一个耳机(Headphone)图标。
要让 iPhone 退出“耳机模式”，请短暂插入并取下耳机。如果这没有帮助，请使用压缩空气或齿间刷清洁耳机插孔或Lightning端口。(Lightning)您可能还想重新启动(restart)或强制重新启动您的 iPhone(force-restart your iPhone)。

上面的指针希望能让你在 iPhone 上取消静音。如果上述建议均无济于事，请考虑将 iPhone 上的设置重置为出厂默认设置（前往Settings > General > Transfer或重置(Reset)iPhone，然后轻点“重置所有设置”(Reset All Settings)）。
如果这仍然没有帮助，您可能正在处理有缺陷的 iPhone 扬声器。检查的最佳方法是访问Settings > Sounds和触觉(Haptics)并将铃声(Ringtone)和警报(Alert)音量滑块向左或向右拖动。如果您的 iPhone 无法发出任何声音，请

Top 7 Ways to Unsilence Calls on iPhone
Does your Αpple iPhone fail to ring for incoming calls? There are several reasons why that happens. Rеad on to learn about the best ways to unsilence calls on thе iPhone.
If your iPhone does not ring for incoming phone calls, the chances are it’s in Silent Mode. If that’s not the reason, it could be an iOS feature, setting, or software conflict preventing it from ringing. The methods below should help you unsilence calls on your iPhone.
1. Turn Off Silent Mode
Silent Mode is the most common reason that stops your iPhone from ringing to incoming Phone and FaceTime calls. To switch to Ring Mode, just flick the Silent switch on the left side of your iPhone (above the Volume buttons) so that the color orange isn’t showing beneath.
A Silent Mode – Off notification should appear on your iPhone’s Home Screen as confirmation.
2. Increase Ringer Volume
It’s also possible you have set the ringer volume on your iPhone at a level that’s too low to hear properly. To check, open the Settings app and tap Sounds & Haptics. Then, drag the slider under Ringtone and Alert Volume to the right to raise the volume.
Optionally, activate the switch next to Change with Buttons if you prefer increasing and decreasing the ringer volume using the iPhone’s Volume Up and Down buttons.
3. Turn Off Do Not Disturb/Focus
Another feature that not only silences phone calls but also blocks them is Do Not Disturb (iOS 14 and earlier) and Focus (iOS 15 and later). To disable it, open the Control Center (swipe down from the top right of the screen or double-click the Home button). Then, tap the Moon icon (DND) or the Profile icon (Focus).
You may also want to check if Do Not Disturb or Focus is set to activate on schedule or allow calls from specific contacts despite having the feature active. For more details, check out how Do Not Disturb and Focus works on the iPhone.
4. Check Your Sleep Schedule
If you have a Sleep schedule set up on your iPhone, it could automatically trigger Do Not Disturb or the Sleep Focus. Consequently, that results in silenced calls.
To stop that, open the Health app, tap Browse, and select Sleep. Then, tap Full Schedule & Options and disable the switch next to Use Schedule for Sleep Focus (or turn off Sleep Schedule if you want to disable your Sleep schedule altogether).
If your iPhone is on iOS 13 or earlier, open the Clock app, tap Bedtime > Options, and turn off the switch next to Do Not Disturb During Bedtime.
5. Disable Silence Unknown Callers
To reduce spam calls, your iPhone has a built-in feature that blocks unknown numbers—those not in your contact list. However, it can also prevent important calls from reaching you and instead send them to your voicemail.
To disable it, open the iPhone’s Settings app, select Phone, and tap Silence Unknown Callers. Then, turn off the switch next to Silence Unknown Callers on the following screen.
6. Disable Bluetooth Devices
If you regularly use Bluetooth audio devices like Apple’s AirPods with your iPhone, don’t forget to turn them off when you aren’t using them. If not, your iPhone will end up alerting you to incoming calls via your Bluetooth headset.
If your Bluetooth headset is not near you, try disabling your iPhone’s Bluetooth radio instead (open the Control Center and tap the Bluetooth icon).
In iOS 14 and later, AirPods and Beats headphones may switch over to your iPhone without permission and create audio issues. To stop that, go to Settings > Bluetooth, tap the Info icon next to AirPods, and set Connect to This iPhone to When Last Connected to This iPhone.
7. Get Out of “Headphone Mode”
If you use a pair of wired headphones, your iPhone might get stuck in “Headphone Mode” even after you remove them. That completely blocks all sound output, including the ringer. When that happens, you will see a Headphone icon on the Volume slider in the Control Center.
To get an iPhone out of “Headphone Mode,” briefly plug in and remove your headphones. If that doesn’t help, clean the headphone jack or the Lightning port with compressed air or an interdental brush. You might also want to restart or force-restart your iPhone.
Ring Ring
The pointers above hopefully allowed you to unmute calls on your iPhone. If none of the suggestions above help, consider resetting the settings on your iPhone to factory defaults (go to Settings > General > Transfer or Reset iPhone, and tap Reset All Settings).
If that still doesn’t help, you might be dealing with a defective iPhone speaker. The best way to check that is to visit Settings > Sounds & Haptics and drag the Ringtone and Alert Volume slider to the left or right. Contact Apple Support if your iPhone fails to emit any sound.
